Thank you for the update Dailonihil. I apologize for the delay in our response.

The graphical requirements for Shadowbringers will be very similar to Stormblood. The kind of performance you are seeing now seems normal for your hardware and is likely what you'll be seeing for the new expansion.

If you want to improve your FPS, you will need to lower some graphical settings. Ambient Occlusion, Reflections and Parallax Occlusion tend to have the biggest impact on FPS.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
